[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figure 1 and Figure 2As shown, this embodiment provides a gas chamber structure for a coal gangue separator, including a chamber body 2. The front of the chamber body 2 has at least three maintenance openings 1. Each maintenance opening 1 is connected to a hinged door 4 that can be flipped up and down. The end of the door 4 away from the hinge 3 is equipped with a tension lock 5 that engages with the maintenance opening 1 of the chamber body 2 (the tension lock 5 adopts a tension lock with a dust cover, self-locking mechanism, and anti-vibration mechanism, as per Chinese patent application number CN202420599629.1). A bubble-sealed sealing strip 6 is fitted to the side of the door 4. When maintenance or repair of the gas chamber is required, the operator only needs to loosen the tension lock. Lock 5 allows the door 4 to be opened upwards via hinge 3, providing direct access to internal components. After maintenance, the door 4 is closed downwards and secured by tightening lock 5. The bubble sealing strip 6 is deformed under pressure, restoring the closed state of the chamber 2. The hinge 3 connects the door 4, which can be flipped up and down, to the maintenance opening 1 of the chamber 2, and the tightening lock 5 facilitates maintenance operations, saves maintenance time, and features a simple structure and easy operation. The bubble sealing strip 6 is installed on the side of the door 4, effectively enhancing the sealing of the chamber 2, preventing dust from entering, ensuring the cleanliness of the equipment interior, and extending its service life.

[0020] A hidden handle 7 is provided at the middle of the end of the door 4 away from the hinge 3. The hidden handle 7 not only makes it easy to open the door 4, but also avoids external protrusions and reduces the possibility of accidental collisions.

[0021] The concealed handle 7 is embedded in the compartment door 4 by a self-matching fastener 8, making the concealed handle 7 more securely installed.

[0022] The self-fitting fastener 8 includes an inwardly recessed mounting groove 9 in the compartment door 4. The mounting groove 9 is equipped with a rubber shell 10 inside. The inner top side of the rubber shell 10 is equipped with a gripper groove 11. The rubber shell 10 has a certain elasticity and wear resistance. The gripper groove 11 is ergonomically designed to facilitate the application of force and improve operating comfort.

[0023] The outer wall of the rubber shell 10 is provided with a protective edge 15. The protective edge 15 is fixedly connected to the door 4 by a locking screw 16. The protective edge 15 can prevent dust and impurities from entering the installation groove 9. The connection method of the locking screw 16 is reliable and easy to disassemble and maintain.

[0024] The inspection opening 1 is provided with a stepped positioning groove 12 that matches the door 4. The stepped positioning groove 12 can guide the door 4 to close accurately and enhance the sealing effect.

[0025] At least two hinges 3 are provided on the same compartment door 4, so that the compartment door 4 can be rotated more smoothly, the force is more even, and the service life is extended.

[0026] Each of the aforementioned door 4 is provided with two tension locks 5. The two tension locks 5 enhance the locking force, improve the sealing reliability, and prevent the door 4 from loosening due to vibration.

[0027] The inner surface of the bubble sealing strip 6 is provided with a T-shaped elastic block 13, and the side of the door 4 is provided with a groove 14 that matches the elastic block 13. The T-shaped elastic block 13 and the groove 14 cooperate to make the installation of the bubble sealing strip 6 more convenient and secure, prevent it from falling off, and also allow the bubble sealing strip 6 to be replaced.

[0028] During operation, when inspection or maintenance of the gas chamber is required, the operator only needs to loosen the tension lock 5, and the chamber door 4 will be opened upwards via the hinge 3 through the hidden handle 7, allowing direct access to the internal components. After maintenance, the chamber door 4 will be closed downwards and secured by the tension lock 5. The bubble sealing strip 6 will deform under pressure to achieve a seal, restoring the chamber body 2 to a closed state. The chamber door 4, which can be flipped up and down, is connected to the maintenance opening 1 of the chamber body 2 via the hinge 3, and together with the tension lock 5, it facilitates maintenance operations, saves maintenance time, and features a simple structure and easy operation. The bubble sealing strip 6 is installed on the side of the chamber door 4, which effectively enhances the sealing of the chamber body 2, prevents dust from entering, ensures the cleanliness of the equipment interior, and extends its service life.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
